HEMAN A. BARNARD, OF MOLIiNE, ILLINOIS, ASSIGNOR TO THE BARNARD & LEAS MANUFACTURING COMPANY, OF SAME PLACE.

GRAIN-SCOURER.

SPECIFICATION formingpart of Letters Patent No. 243,830, dated July 5, 1881.

' Application filed April 4, 1881. (No model.)

To all whom it may concern:

Be it known that I, HEMAN A. BARNARD, of Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Grain-Scourers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,

to which form part of this specification, in which-- Figure l is a perspective, and Fig. 2 a bottom, view of my invention.

This invention relates to that class of apparatus for scouring grain in which the series of rubbers or heaters are arranged alternately with brushes and tangentially to the periphery of the cylinder carrying the same. Experience has demonstrated that with the beaters so arranged it is impossible to subject the grain to a sufficient amount of friction to scour it. This will be apparent from the fact that only a limited portion of the face of each beater-rod can perform the office of rubbing the wheat against the casing.

It is the object of my invention to remedy this defect and to provide a more perfect grainscouring machine.

With this object in view my invention consists in utilizing the whole surface or the entire 0 faces of the heaters by arranging them parallel to the periphery of the skeleton-formed cylinder and the brushes, so that they will travel in the same plane of motion, as will be hereinafter more fully set forth.

3 5 As my invention relates solely to the specific features above mentioned, and as grain-scourers are very well known, it will be unnecessary to describe in detail the remaining parts of the machine.

Referring by letter to the drawings, A indicates the brush and beater cylinder, which is provided with a series of brushes, B, at its periphery and concentric with said cylinder.

The letter 0 indicates the beater-sections,

that are constructed of the longitudinal round 5 rods E, which pass through the top and bottom plates at their ends, and are thereby secured. The beater-rods also pass through peripheral braces F, one of which is provided for each section. These peripheral braces are secured at their ends to longitudinal fiat bars G by means of screws or bolts passing through ears H at, the ends of the braces. The said flat bars G are arranged at the sides of the brushes and constitute the sides of the receptacles in which the brushes are held. The said fiat bars G are also secured in any suitable manner at their ends to the top and bottom plates. The rods of each section are held parallel with the axis of the cylinder, and the said rods are also placed uponan arc concentric with the face of the cylinder. The are of one beatersection is in continuation of the are described by the face of the adjacent brush, and so on around the cylinder, whereby during operation the brushes and the heaters will travel in the same plane of motion, and a large portion of each beater-rod be brought to act against the grain. The above arrangement admits of the perfect action of all of the heaters at one and the same time upon the grain.

Having thus described my invention, what 1 claim, and desire'to secure by Letters Patent, 1s--- The within-described grain-scouring cylinder, of skeleton form, provided with a series of brushes and beater-sections arranged alternately to each other, the latter composed of a series of rods rounded on their faces, all of which are arranged on a circle with the brushes and parallel with the periphery of the cylinder, as and forthe purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

HEMAN A. BARNARD.
